while defining surface goal of torque which surfaces should selected???

i want the defination of torque n the month when ssi report is done

please i want detailed information on professional development workshops

All the face that will ganerate torque in the direction should be selected.

ok it means faces perpendicular to axis to rotation is not required to select as it will not produce torque..

jeremy,

if you are pump user then tell from your experience how much diviation u found for torque or efficiency compared to tested one ?

Sorry ,I have no such data if you have a test data of a pump I can help you to simulate it.
